[R] boxplot() from list

[Laura Quinn]

I have a list containing 48 objects (each with 30 rows and 4 columns, all
numeric), and wish to produce 4 boxplot series (with 48 plots in each) ,
one for each column of each object.

Basically I want a boxplot from boxplot(mylist[[]][,i])

for i in 1:4. It seems that I can create a boxplot of length 48 from the
entire list, but I don't seem able to subscript to return 4 boxplots from
the list - I have also tried to create 4 new lists (one for each column of
each object) by using variations on the following, but none seems to work:

newlist<-oldlist[,1]
newlist<-oldlist[[]][,1]
newlist<-oldlist[[]][,$colone]

can anyone please offer some insight??

Thanks in advance,
